Add Cancel Upload option

[RoseBunker]

Problem

Selected the wrong image to upload, and because it was a big file I had to wait ages for it to finish uploading before I could then delete it.

Solution

Add an 'X' button to the upload progress bar to cancel upload of image mid-upload. Not a massive thing, but rather a nice touch to have, could help streamline CURATE for users and also prevent unnecessary data storage being used.
